I found a case where the behavior on the feature/noverlay differs from
mainline.
(ert-deftest overlays-in-empty-range ()
(with-temp-buffer
(insert (make-string 10 ?=))
(make-overlay 5 7 nil nil t)
(should (equal nil (overlays-in 5 5)))))
On mainline the above test passes. On noverlay it returns the overlay
and fails.
I found this a randomized diff test harness I hacked up. I don't know
if any packages will break due to this difference.
The docs for `overlays-in' say this:
> Overlap means that at least one character is contained within the
> overlay and also contained within the specified region.
Since no character can be contained within the region (5 5) I think
mainline has it right here.

Thanks for the prompt. Closing, since I think the bug is fixed.
